Abstract: A method includes receiving a data retrieval request. A plurality of identifiers are determined in accordance with the data retrieval request. Integrity information is generated based on determining the plurality of identifiers by performing a cyclic redundancy check. Stored integrity information corresponding to the data retrieval request is compared with the integrity information, where the stored integrity information was previously generated by performing the cyclic redundancy check. When the stored integrity information compares unfavorably with the integrity information, corruption associated with the plurality of identifiers is determined.

Abstract: Methods and apparatus for selection of memory devices in a distributed storage network. In an example, a computing device receives a data object for storage and selects a set of storage nodes of a plurality of sets of storage nodes for storing the data object. Selection of the set of storage nodes includes determining storage attributes associated with each set of storage nodes of the plurality of sets of storage nodes. Selection of the set of storage nodes additionally includes determining a storage preference associated with the data object, and comparing the storage preference with the storage attributes of the plurality of sets of storage nodes to determine a best match. Following selection of a set of storage nodes, the computing device facilitates storage of the data object in the selected set of storage nodes.

Abstract: Methods and apparatus for selection of memory devices in a distributed storage network. In an embodiment, a computing device receives a data object for storage and forwards the data object to a buffer for temporary storage, the buffer comprised of a first memory devices of a first memory type. A system level storage efficiency is determined for the data object based, at least in part, on a data attribute associated with the data object. Second memory devices, of a second memory type, are selected based on the system level storage efficiency preference, and compatible dispersed storage error encoding parameters for the data object are determined. The data object is encoded using the encoding parameters to generate a plurality of encoded data slices, which are provided to the second plurality of memory devices for storage. Further, system addressing information is generated based on an identifier associated with the data object.

Abstract: A method for execution by a processing module of a storage network includes determining processing parameters for data based on a number of storage and execution units of the storage network to be utilized in processing the data, where the data is associated with a task. The method further includes task partitioning of the task based on the number of storage and execution units and the processing parameters. The method further includes processing the data in accordance with the processing parameters to produce slice groupings. The method further includes partitioning the task based on the task partitioning to produce partial tasks. The method further includes sending the slice groupings and corresponding partial tasks to the storage and execution units.

Abstract: A storage network operates by: receiving a plurality of identifiers associated with a user including a user identifier and a group identifier; generating a plurality of key pairs associated with the plurality of user identifiers, the plurality of key pairs including a first key pair and a second key pair, the first key pair including a first public key and a first private key, and the second key pair including a second public key and a second private key; storing the plurality of key pairs; generating at least one request for a certificate; receiving at least one signed certificate in response to the at least one request; and accessing the storage network using the at least one signed certificate.

Abstract: A method for execution by one or more computing devices of a storage network includes determining an encoded data slice of a set of encoded data slices needs rebuilding during an encoded data slice reduction operation. The method further includes determining whether a current number of encoded data slices of the set of encoded data slices that are not in need of rebuilding is less than a reduced rebuild threshold number associated with the encoded data slice reduction operation. When the current number is less than reduced rebuild threshold number, the method further includes rebuilding the encoded data slice.

Abstract: A storage unit of the storage network operates by: receiving an access request from a user device of a first group of user devices, the storage unit having an access policy that designates, for the first group of user devices, a first read time window for reading data from the storage unit and a first write time window for writing data to the storage unit; determining whether the access request is received within the first read time window when the access request is a read request or whether the access request is received within the first write time window when the access request is a write request; when the access request is the read request and is received within the first read time window, generating a read response that includes one or more requested encoded data slices; and when the access request is the write request and is received within the first write time window, processing the write request to store one or more new encoded data slices.
